Water Proofing

Problem

Many homeowners are extending their properties outwards and upwards instead of moving to a larger property. Now, as waterproofing methods and technologies become more advanced but also, more economically viable, there is a growing trend of homeowners utilising existing damp and dank cellars by doing a basement conversion and converting basements into bright and comfortable habitable living areas.

However, the walls and floors in rooms below ground level, such as a basement, are at risk of damp. As these areas are below ground level it is impossible to completely remove moisture. However, using specialist water proofing techniques JCJ Damp Proofing can achieve a dry and habitable basement or cellar, whether it be a new or existing construction.

Solution

Traditional methods of basement waterproofing such as cement based renders, often referred to as ‘basement tanking’ are becoming less reliable as water table levels rise and bring increased hydrostatic pressure to bear on properties.

The new but increasingly used solution is to apply a Polyethylene sheet material described as Cavity Drain Membrane which, provided the substrate is suitable, can be directly applied with little preparation to the walls. Cavity membrane is both vapour proof and impervious to water and provides additional insulation value.

JCJ Damp Proofing would install a full cavity drainage system which incorporates a wall and floor studded membrane, which will allow for movement of water behind, whilst keeping your finished surface dry.

The membrane is linked to a drainage channel at the base of the wall, which will collect any water and either direct it to existing drainage or a pump to remove it from your property.

The wall membrane can be finished with either plasterboard on a stud wall, drywall adhesive, or have plaster applied directly, depending on the most suitable approach.

Benefits

The membrane is fixed directly to the existing wall finish and requires minimum preparation.

There is no drying time required with this system so finishing works can be started immediately after the waterproofing is completed.

Both wall and floor membranes allow for movement within the property so settlement or cracking isn’t an issue.
